Back in November, the internet pretty much burst into flames after Marvel released the first trailer for Avengers: Infinity War. Obviously, there is a lot to digest in the epic, action-packed footage, especially now that there's another new trailer added into the mix. We were quick to count all the character appearances, giggle over Thanos's interesting makeover, and gawk at the infinity stones. But there's something much more sinister and subtle lurking in both trailers that we need to address: the potential death of Iron Man. And, for the record, Iron Man 4 has not been announced or confirmed.

It's not just that Iron Man looks like he's in grave danger — he takes a pretty hard punch to the face, and Thanos seems to ominously tell him, "I hope they remember you." Rumors of Robert Downey Jr.'s exit from the Marvel Comics Universe have been swirling for a while now. The actor hinted at his retirement as far back as 2013. Even more damning, he just said this past Summer, "I just want to hang up my jersey before it's embarrassing." Even Avengers director Joe Russo said in a 2016 interview with Forbes that the Marvel universe could go on for another phase or two before we "need to see" Iron Man again.

In the case of Avengers: Infinity War, tons of fans have already theorized about Iron Man's death on the open forum of the internet. While some would actually be glad to see him go for whatever reason, some are devastated by the idea and willing to forego Marvel entirely. One person, who may or may not have been joking, seems to think Iron Man is somehow involved in DC Comics's Justice League. Sounds like things are really going to explode in a big way once the film hits theaters.
